Building the split device-tree tree[0] highlighted that upstream commit
9eec6cb142bd ("powerpc/44x/fsp2: Add device tree for FSP2 board") introduced
this warning when building the device tree:$ make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc fsp2.dtb CHK scripts/mod/devicetable-offsets.h DTC arch/powerpc/boot/fsp2.dtb arch/powerpc/boot/fsp2.dtb: Warning (reg_format): "reg" property in /sdhci@020c0000 has invalid length (8 bytes) (#address-cells == 2, #size-cells == 1) This commit adds the second adress cell as zeroes to resolve the warning. Note: I have no access to or information about this platform so this is purely a guess as to the fix. An alternative would be to adjust #address-cells, but whether that is correct or not depends on the platform.
